#Considerateness.# *99* We should, therefore, in our dealings with people show what I may almost call reverence toward all men--not only toward the men who are the best, but toward others as well. For indifference to public opinion implies not merely self-sufficiency, but even total lack of principle. There is, too, a difference between justice and considerateness in one's relations to one's fellow-men. It is the function of justice not to do wrong to one's fellow-men; of considerateness, not to wound their feelings; and in this the essence of propriety is best seen. With the foregoing exposition, I think it is clear what the nature is of what we term propriety. #Duties prescribed by propriety:# *100* Further, as to the duty which has its source in propriety, the first road on which it conducts us leads to harmony with Nature and the faithful observance of her laws. #(1) Follow Nature,# If we follow Nature as our guide, we shall never go astray, but we shall be pursuing that which is in its nature clear-sighted and penetrating (Wisdom), that which is adapted to promote and strengthen society (Justice), and that which is strong and courageous (Fortitude). But the very essence of propriety is found in the division of virtue which is now under discussion (Temperance). For it is only when they agree with Nature's laws that we should give our approval to the movements not only of the body, but still more of the spirit. #(2) subject appetite to reason.# *101* Now we find that the essential activity of the spirit is twofold: one force is appetite (that is, ὁρμή, in Greek), which impels a man this way and that; the other is reason, which teaches and explains what should be done and what should be left undone. The result is that reason commands, appetite obeys. XXIX. Omnis autem actio vacare debet temeritate et neglegentia nec vero agere quicquam, cuius non possit causam probabilem reddere; haec est enim fere discriptio[93] officii. *102* Efficiendum autem est, ut appetitus rationi oboediant eamque neque praecurrant nec propter pigritiam aut ignaviam deserant sintque tranquilli atque omni animi perturbatione careant; ex quo elucebit omnis constantia omnisque moderatio. Nam qui appetitus longius evagantur et tamquam exsultantes sive cupiendo sive fugiendo non satis a ratione retinentur, ii[94] sine dubio finem et modum transeunt; relinquunt enim et abiciunt oboedientiam nec rationi parent, cui sunt subiecti lege naturae; a quibus non modo animi perturbantur, sed etiam corpora. Licet ora ipsa cernere iratorum aut eorum, qui aut libidine aliqua aut metu commoti sunt aut voluptate nimia gestiunt; quorum omnium voltus, voces, motus statusque mutantur.
